The internal face of copper pipe is stated to be smooth, outside wall surface is screw thread；The excircle of the drive end bearing bracket is connected to the front end of the shell,
The drive end bearing bracket is provided with medium inlet and media outlet, and the medium inlet is located at lower half, and the media outlet is located at upper
Half portion；The middle of the inside of the drive end bearing bracket is provided with the lagging of right-angled intersection and perpendicular baffle, so as to by the drive end bearing bracket
Inner space be divided into upper left quarter, lower left quarter, upper right quarter and right lower quadrant；The copper pipe is divided into two as medium channel
System, a system is that medium enters copper pipe from lower left quarter, is gone out copper pipe from upper left quarter, another system be medium from right lower quadrant into
Enter copper pipe, go out copper pipe from upper right quarter；The rear end cap is welded in the rear end of the shell, the rear end cap by cylindrical shell and
Spherical calotte is welded, and the cylindrical shell is connected with the rear end of the shell；The spoiler be more than semicircle discount vibram outlet, cloth
It puts mode to arrange along the enclosure proportional spacing for part, the discount vibram outlet of adjacent spoiler is located above and below vertical respectively
Both sides make the runner in the shell form the passage for the turbulent flow that teeters.
Shell of the present invention is relatively thin housing, can not employ the form installation front-end and back-end of bolt or flange
Component, therefore after first welded and installed noseplate and rear bottom plate, it is possible to opened up on noseplate and rear bottom plate bolt hole or
Flange hole is easily installed other component.

Specific embodiment
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
Heat pump air conditioner flow-disturbing dual system dry type heat exchanger, including shell 1, copper pipe 2, drive end bearing bracket 3, rear end cap 4 and spoiler
5；The both ends of the shell 1 are respectively welded noseplate 15 and rear bottom plate 16, and the noseplate 15 is circular slab, is welded in institute
The front end of shell 1 is stated, offers hole；Bottom plate 16 is Circular Plate after described, is welded in the rear end of the shell 1；It is described outer
Shell 1 is relatively thin housing, can not employ the component of the form installation front-end and back-end of bolt or flange, therefore first welding peace
After filling noseplate 15 and rear bottom plate 16, it is possible to open up bolt hole or flange hole on noseplate 15 and rear bottom plate 16, be convenient for
Other component is installed.The copper pipe 2 is entered by the lower half of the drive end bearing bracket 3 in the shell 1, in stretching, extension in the shell 1
It is turned back again to the first half of the drive end bearing bracket 3 to the rear end of the shell 1；The internal face of the copper pipe 2 is smooth, outside wall surface
For screw thread；The flow resistance of the inner wall smooth of the copper pipe 2 then fluid media (medium) is smaller, and can improve efficiency reduces energy consumption；Institute
